Ivanka Trump, the US president’s daughter, and her husband Jared landed at Ben-Gurion Airport on Sunday ahead of the opening ceremony for the American embassy in Jerusalem on Monday.

Trump is leading the American delegation to the ceremony alongside US Secretary of the Treasury Steven Mnuchin.

“With great joy, I am returning to Jerusalem,” Ivanka wrote on her Instagram page on Saturday.

“I am honored to join the distinguished delegation representing President Trump, his Administration, and the American people at this momentous ceremony commemorating the opening of our new US Embassy in Jerusalem, Israel,” she added.

“We look forward to celebrating Israel’s 70th anniversary and the bright future ahead. We will pray for the boundless potential of the future of the US-Israel alliance, and we will pray for peace,” Ivanka concluded.

The American delegation will number 250 people, including Congressmen, rabbis and administration officials. It will also include Deputy Secretary of State John Sullivan, Trump’s envoy to the Middle East Jason Greenblatt, American Ambassador David Friedman, Florida Governor Rick Scott, Senators Lindsey Graham, Ted Cruz, Mike Lee and Dean Heller, and Congressmen Joe Wilson and Ted Deutch.

The US State Department stressed on Saturday that “Moving our Embassy is not a departure from our strong commitment to facilitate a lasting peace deal; rather it is a necessary condition for it. We are not taking a position on final status issues, including the specific boundaries of Israeli sovereignty in Jerusalem, nor on the resolution of contested borders.

“Consulate General Jerusalem will continue to operate as an independent mission with an unchanged mandate responsible for US relations with the Palestinians and the Palestinian Authority. The United States continues to support the status quo with regard to the Haram al-Sharif/Temple Mount. The Administration is firmly committed to pursuing a lasting and comprehensive peace between Israel and the Palestinians that promises a brighter future for both.”

Prime Minister Netanyahu will host a gala reception for the American delegation on Sunday afternoon.

Among the 800 invited are 86 foreign diplomats. While most of the European ambassadors have decided to boycott the event, ambassadors from Hungary, the Czech Republic, Romania and Austria will be among the 40 ambassadors attending. The Bulgarian ambassador might attend as well.

The Foreign Ministry has decided to allow all Knesset members to attend the reception, after being criticized for only inviting members of the coalition and members of the Knesset’s Foreign Affairs and Defense Committee.

“We misestimated the demand,” said a Foreign Ministry official. “As soon as we realized that there was a lot of interest in the event, we decided to open it to everyone.”

The official embassy opening ceremony will kick off at 4 pm Monday with about 800 participants. It will begin with the American anthem and opening remarks from Ambassador Friedman, who will invite a priest and a rabbi to offer their blessings. The ceremony will include speeches by Netanyahu, Mnuchin and Sullivan, followed by a televised greeting from President Trump. Singer Aveva Dese and her band will perform the songs “Jerusalem of Gold” and “Jerusalem.”

The embassy’s official sign with a dedication plaque for President Trump and Vice President Pence will be unveiled, followed by speeches from President Reuven Rivlin and Kushner.

The embassy’s mezuzah will be affixed by Ambassador Friedman on Wednesday.

At the same time, the Israeli Embassy in Washington will host a special event in honor of the embassy move and Israel’s 70th anniversary. The guest of honor will be Vice President Pence, who will also speak at the event.
